This application claims priority to Chinese Patent Application No. 202210951471.5, filed with the China National Intellectual Property Administration on Aug. 9, 2022 and entitled “STYLUS-BASED USING METHOD AND APPARATUS”, which is incorporated herein by reference in its entirety.

This application relates to the field of terminal technologies, and in particular, to a stylus-based using method and apparatus.

With the popularization and development of the Internet, people's functional requirements for electronic devices are also becoming increasingly diverse. For example, to simplify a manner of using the electronic devices, styluses gradually become an important tool for inputting data into the electronic devices or controlling the electronic devices.

Generally, a stylus is wrapped with a touch film at a position close to a tip of the stylus, so that the stylus can realize functions such as controlling an electronic device based on a trigger operation performed by a user on the touch film, and the like.

However, accuracy of the foregoing stylus-based using method is low, affecting user experience of controlling the electronic device by using the stylus.

Embodiments of this application provide a stylus-based using method and apparatus, so that accuracy of operation identification can be improved by identifying trigger data in a first region where a touch film overlaps with a facet, thereby improving user experience of controlling an electronic device by using the stylus.

According to a first aspect, an embodiment of this application provides a stylus-based using method. A part or all of a body of the stylus is surrounded by a touch film. A facet is disposed on the body of the stylus. The touch film includes a first region. The first region is smaller than a body region covered by the touch film and the first region is located at a position in the facet. The method includes: When the stylus receives a first operation on the first region, the stylus identifies the first operation to obtain an identification result, and controls a target device based on the identification result. The target device establishes a communication connection to the stylus. In this way, accuracy of operation identification can be improved by identifying trigger data in the first region where the touch film overlaps with the facet, thereby improving user experience of controlling the target device by using the stylus.

The first region may be a preset region described in embodiments of this application. The target device may be an electronic device described in embodiments of this application.

In a possible implementation, when the first operation is a slide operation toward a position away from a tip of the stylus, the identification result indicates the target device to flip to a next page. Alternatively, when the first operation is a slide operation toward a position close to a tip of the stylus, the identification result indicates the target device to flip to a previous page. In this way, the stylus may control, based on a slide operation performed by a user on the first region, the target device to perform page flipping, so as to avoid a false touch caused when the user triggers another position of the touch film, thereby improving accuracy of controlling the target device by the user by using the stylus.

In a possible implementation, the method further includes: The stylus obtains status information of the stylus, where the status information of the stylus indicates an orientation of the tip of the stylus. That the stylus identifies the first operation to obtain an identification result, and controls a target device based on the identification result includes: The stylus identifies the first operation and the status information to obtain the identification result, and controls the target device based on the identification result. In this way, the stylus may perform page flipping control on the target device based on both the orientation of the tip of the stylus and the slide operation on the first region, so that the user can flexibly control the target device by using the stylus.

In a possible implementation, when the status information satisfies a preset condition and the first operation is a slide operation toward a position away from the tip of the stylus, the identification result indicates the target device to flip to a next page. Alternatively, when the status information does not satisfy a preset condition and the first operation is a slide operation toward a position away from the tip of the stylus, the identification result indicates the target device to flip to a previous page. Alternatively, when the status information satisfies a preset condition and the first operation is a slide operation toward a position close to the tip of the stylus, the identification result indicates the target device to flip to a previous page. Alternatively, when the status information does not satisfy a preset condition and the first operation is a slide operation toward a position close to the tip of the stylus, the identification result indicates the target device to flip to a next page. In this way, the stylus may perform page flipping control on the target device based on both the orientation of the tip of the stylus and the slide operation on the first region, so that the user can flexibly control the target device by using the stylus.

The preset condition may be that the tip faces up as described in embodiments of this application. The preset condition is not satisfied may be that the tip faces down as described in embodiments of this application.

In a possible implementation, the method includes: The stylus is switched from a first mode to a second mode. In the first mode, the stylus is capable of responding to a trigger operation at any position of the touch film. In the second mode, the stylus is capable of responding to a trigger operation in the first region, and does not respond to a trigger operation in the second region that is other than the first region and that is in the touch film. That the stylus receives a first operation on the first region includes: The stylus in the second mode receives the first operation on the first region. In this way, before controlling the target device, the stylus may be switched from the first mode to the second mode, and receive, in the second mode, an operation performed by the user on the first region, so as to avoid receiving, in the first mode, a false touch caused when the user performs the first operation on the first region.

The first mode may be a writing mode described in embodiments of this application. The second mode may be a page flipping stylus mode described in embodiments of this application.

In a possible implementation, the stylus includes a touch integrated circuit IC and a microcontroller unit MCU. The method further includes: The MCU sends a first instruction to the touch IC, where the first instruction indicates the stylus to switch from the first mode to the second mode. The touch IC obtains, based on the second mode, first trigger data corresponding to the first operation, and sends the first trigger data to the MCU. That the stylus identifies the first operation includes: The MCU identifies the first trigger data. In this way, the touch IC in the stylus may obtain, based on the second mode, only the first trigger operation corresponding to the first operation, thereby reducing memory occupation caused by obtaining the trigger operation in the second region.

In a possible implementation, the stylus includes a touch IC and an MCU. The method further includes: The touch IC obtains second trigger data, and sends the second trigger data to the MCU. The second trigger data is trigger data for the touch film, and the second trigger data includes the first trigger data corresponding to the first operation. That the stylus identifies the first operation includes: The MCU identifies the first trigger data based on the second mode. In this way, the MCU in the stylus may receive the second trigger data sent by the touch IC, and screen out the first trigger data by using the second mode, so that accuracy of operation identification by the stylus based on the first trigger data can be improved.

In a possible implementation, that the stylus identifies the first operation to obtain an identification result, and controls a target device based on the identification result includes: The stylus identifies the first operation to obtain the identification result, and controls movement of a cursor in the target device and/or a change of a page of the target device based on the identification result. In this way, the stylus can not only implement page flipping on the target device, but also control the movement of the cursor and the change of the page of the target device, thereby improving flexibility of controlling the target device.

In a possible implementation, when the status information satisfies a preset condition and the first operation is a slide operation toward a position away from the tip of the stylus, the identification result indicates the target device to flip to a next page. Alternatively, when the status information does not satisfy a preset condition and the first operation is a slide operation toward a position away from the tip of the stylus, the identification result indicates the target device to flip to a previous page. Alternatively, when the status information satisfies a preset condition and the first operation is a slide operation toward a position close to the tip of the stylus, the identification result indicates the target device to flip to a previous page. Alternatively, when the status information does not satisfy a preset condition and the first operation is a slide operation toward a position close to the tip of the stylus, the identification result indicates the target device to flip to a next page.

1 FIG. 1 FIG. For example,is a schematic diagram of a scenario according to an embodiment of this application. In the embodiment corresponding to, an example in which an electronic device is a tablet is used for description. This example shall not be construed as a limitation on embodiments of this application.

1 FIG. 200 100 100 200 200 As shown in, the scenario may include an electronic deviceand a stylus. The stylusmay be configured to input data to the electronic device, or may be configured to control the electronic device.

100 200 100 200 100 200 200 100 Generally, both the stylusand the electronic devicemay support two operation modes, for example, a writing mode and a page flipping stylus mode. The writing mode may be a default mode of the stylus. In the writing mode, a user may perform writing in a touchscreen of the electronic deviceby using the stylus, so as to input data to the electronic device. In the page flipping stylus mode, page flipping control of the electronic devicemay be implemented based on an operation performed by the user gripping and sliding the stylusup and down (or left and right) in the touch film.

It may be understood that the touch film may be a component that surrounds a front end of the stylus and that is configured to receive a trigger operation performed by the user. For example, the touch film may be configured to receive an operation performed by the user sliding up and down (or left and right) in the page flipping stylus mode.

2 FIG. 2 FIG. 2 FIG. 2 FIG. For example,is a schematic diagram of a touch film of a stylus according to an embodiment of this application. As shown in a in, a front end that is of the stylus and that is at a position close to a tip of the stylus is surrounded by the touch film. The touch film may be a position corresponding to a gray region shown in a in. As shown in b in, when the touch film is unfolded, the touch film may be a rectangular region with a width of W and a height of H.

3 FIG. 3 FIG. 3 FIG. 3 FIG. Generally, after a user triggers the touch film, the stylus may receive and identify operation data at any position in the touch film. For example, in a page flipping stylus mode, a grip posture at which the user triggers the stylus is described by using an example in which the user implements page flipping control on an electronic device based on the stylus. For example,is a schematic diagram of grip postures according to an embodiment of this application. It may be understood that a stylus may implement page flipping control on an electronic device based on identification of the grip posture for a touch film in any one of a in, b in, or c in.

However, because the grip posture at which the user triggers the touch film varies, the stylus is prone to mistakenly considering that trigger of the touch film by a palm or a finger of the user is a page flipping operation in the page flipping stylus mode, resulting in low accuracy of trigger operation identification by the stylus, and affecting user experience of controlling the electronic device by using the stylus.

In view of this, this embodiment of this application provides a stylus-based using method. The stylus is surrounded by the touch film at a position close to a tip of the stylus. The stylus receives a first operation on the touch film. In response to the first operation, the stylus identifies an operation in the first region of the touch film to obtain an identification result, so that a false touch caused when the user triggers another position of the touch film can be avoided based on the identification of the operation in the first region by the stylus, and accuracy of controlling the electronic device by the user by using the stylus is improved. The first region is smaller than a region corresponding to the touch film.

6 FIG. 6 FIG. 602 As shown in a in, the stylus may divide a touch film with a width of W and a height of H into a plurality of channels of a size such as 6×6, and identify the trigger operation in the page flipping stylus mode based on a trigger operation that is performed by the user on the preset regionof a size such as 1×4 and that is on a facet shown in b in, so as to control an electronic device by using an identification result.

602 602 The preset regionof the size such as 1×4 may satisfy a size of a finger when the user performs single finger trigger. It may be understood that in this way, a false touch caused when a plurality of fingers perform trigger in the preset regioncan be avoided, and accuracy of operation identification is improved.

602 In a possible implementation, the size of the preset regionat the position in the facet may alternatively be a size such as 1×3, 1×5, 1×6, or the like.

602 It may be understood that the preset region may be understood as a strip region disposed at the facet of the body of the stylus. The size of the preset region may be related to a size of a grid that is caused by division of the touch film, a size of the facet, and a size of a finger. For example, when the touch film is divided into 12×12 grids, the size of the preset regionmay be a size such as 2×6, 2×7, 3×7, or the like. This is not limited in embodiments of this application.

It may be understood that the 6×6 size division of the touch film and the size 1×4 corresponding to the preset region are merely used as examples. These examples shall not be construed as a limitation on embodiments of this application. For example, when the touch film is divided into a plurality of 5×5 channels, the size of the preset region may alternatively be 1×3, 1×4, 1×5, or the like. Alternatively, when the touch film is divided into a plurality of 7×7 channels, the size of the preset region may be 1×3, 1×4, 1×5, 1×6, 1×7, or the like. This is not limited in embodiments of this application.

It may be understood that, to prevent the stylus from identifying a trigger operation at any position in the touch film, which makes accuracy of identifying the trigger operation performed by the user low, the stylus may identify a trigger operation on the preset region that is at the position in the facet and that is in the touch film, and ignore a trigger operation at another position that is other than the preset region and that is in the touch film, so as to reduce a false touch condition, and further improve accuracy of trigger operation identification by the stylus.

6 FIG. 7 FIG. 7 FIG. Based on the embodiment corresponding to, an embodiment of this application provides a stylus-based using method. For example,is a schematic flowchart of a stylus-based using method according to an embodiment of this application. In the embodiment corresponding to, the stylus-based using method may relate to an electronic device and the stylus. An example in which the electronic device may be a tablet and the stylus includes a touch IC and an MCU is used for description. This example shall not be construed as a limitation on embodiments of this application.

7 FIG. As shown in, the stylus-based using method may include the following steps.

701 S: The electronic device establishes a communication connection to the stylus.

The stylus and the electronic device may be interconnected through a communication network to realize wireless signal interaction. The communication network may be but is not limited to a short-distance communication network such as a Wi-Fi hotspot network, a Wi-Fi peer-to-peer (peer-to-peer, P2P) network, a Bluetooth network, a zigbee network, or a near field communication (near field communication, NFC) network. This is not limited in embodiments of this application.

It may be understood that, in this embodiment of this application, an example in which the stylus establishes a Bluetooth connection to the electronic device is used for description.

702 S: The electronic device enables a page flipping stylus mode.

It may be understood that, because the stylus enters a writing mode by default when the stylus is started, the page flipping stylus mode may be enabled by using a trigger operation performed by a user on the electronic device.

8 FIG. For example,is a schematic diagram of interfaces for enabling a page flipping stylus mode according to an embodiment of this application.

8 FIG. 8 FIG. 801 When the electronic device receives an operation of enabling a setting function by the user, the electronic device may display an interface shown in a in. In the interface shown in a in, the interface may include a text boxfor searching for a setting item, a control for viewing account information, a control for setting a WLAN, a control for setting Bluetooth, a control for setting a mobile network, a control for viewing a super terminal, and the like. The account information may be 1234567XXXX. The operation of opening the setting function by the user may be a trigger operation performed by the user on a control corresponding to the setting function in a desktop of the electronic device, may be a trigger operation performed by the user on a thumbnail corresponding to the setting function in a multi-task background interface of the electronic device, may be a voice operation, or the like. This is not limited in embodiments of this application. The trigger operation may be a tap operation, a long press operation, a slide operation, a voice operation, another gesture operation, or the like. This is not limited in embodiments of this application.

8 FIG. 8 FIG. 8 FIG. 801 802 In the interface shown in a in, when the electronic device receives that the user inputs and searches for “Demonstrate the page flipping stylus mode” in the text boxfor searching for the setting item, the electronic device may open a function interface corresponding to “Demonstrate the page flipping stylus mode”, and display an interface shown in b in. In the interface shown in b in, the interface may include a controlfor enabling the page flipping stylus mode, and prompt information corresponding to enabling the page flipping stylus. The prompt information may be displayed as follows: After the page flipping stylus mode is enabled, the stylus may be used to control the electronic device to implement functions such as page flipping.

8 FIG. 802 703 In the interface shown in b in, when the page flipping stylus mode is in a disabled status and when the electronic device receives a trigger operation performed by the user on the controlfor enabling the page flipping stylus mode, the electronic device may perform the step shown in S.

703 In a possible implementation, the stylus may alternatively enable the page flipping stylus mode based on a trigger operation performed by the user on the stylus that is in a writing mode. For example, the stylus may be switched from the writing mode to the page flipping stylus mode based on a plurality of tap operations performed by the user on the touch film, or based on operations such as pressing a tip of the stylus by the user for a long time or for a plurality of times, so that the stylus performs the step shown in S.

703 S: The electronic device sends, to the stylus, a message that indicates the stylus to switch to the page flipping stylus mode.

For example, when the electronic device implements a communication connection with the stylus through Bluetooth, the electronic device may send, to the stylus through Bluetooth or the like, the message that indicates the stylus to switch to the page flipping stylus mode. Accordingly, the stylus may receive the message that is sent by the electronic device and that indicates the stylus to switch to the page flipping stylus mode.

704 S: When the stylus receives a trigger operation performed by the user on the touch film, the stylus identifies a trigger operation in a preset region of the touch film to obtain an identification result.

In this embodiment of this application, when the stylus receives the trigger operation performed by the user on the touch film, the stylus may identify the trigger operation in the preset region of the touch film in the following two manners.

In an implementation, when the stylus receives the message that is from the electronic device and that indicates the stylus to switch to the page flipping stylus mode, an MCU in the stylus may send an indication message that includes the page flipping stylus mode to the touch IC, to indicate the touch IC to receive only the trigger operation corresponding to the preset region. Further, the touch IC may send, to the MCU, trigger data corresponding to the trigger operation received in the preset region, and the MCU identifies the trigger data to obtain an identification result. The trigger data may include a position corresponding to the trigger operation, a capacitance value change during the trigger, and the like.

The touch IC may enable, based on the indication message that indicates the page flipping stylus mode, only some channels corresponding to the preset region to receive the trigger operation, so that the touch IC can receive the trigger operation corresponding to the preset region, to obtain the trigger data corresponding to the trigger operation.

It may be understood that, even if the user triggers a region that is other than the preset region and that is in the touch film, the touch IC cannot identify a trigger operation performed by the user.

In another implementation, the touch IC may normally receive a trigger operation performed by the user at any position of the touch film, and send trigger data corresponding to the trigger operation to the MCU. The MCU may identify, based on the received message that indicates the stylus to switch to the page flipping stylus mode, the trigger data corresponding to the preset region, to obtain an identification result. Alternatively, it may be understood that the MCU may filter out the trigger data of the region that is other than the preset region and that is in the touch film.

The touch IC may send the trigger data and a channel corresponding to the trigger data to the MCU together, so that the MCU can identify, based on the message that indicates the stylus to switch to the page flipping stylus mode, the trigger data on the channel in which the preset region is located, to obtain the identification result.

6 FIG. For a meaning of the preset region, refer to the descriptions of the embodiment corresponding to. Details are not described herein again.

705 S: The stylus sends, to the electronic device, a message that indicates the identification result.

For example, the stylus may alternatively send, in a Bluetooth-based manner to the electronic device, the message that indicates the identification result. Accordingly, the electronic device may receive the identification result sent by the stylus.

706 S: The electronic device controls the electronic device based on the identification result.

9 FIG. 10 FIG. In this embodiment of this application, in the page flipping stylus mode, a plurality of manners for controlling the electronic device by using the stylus may be provided. For example, the user may simulate a laser pointer based on the trigger operation on the stylus, to display a laser spot in the electronic device (refer to the embodiment corresponding to). Alternatively, the user may implement page flipping control on the electronic device based on the trigger operation performed by the user on the stylus (refer to the embodiment corresponding to).

In an implementation, the user may simulate the laser pointer based on the trigger operation on the stylus, to display the laser spot in the electronic device.

9 FIG. For example,is a schematic diagram of scenarios in which a laser pointer is simulated based on a stylus according to an embodiment of this application.

9 FIG. 704 705 901 706 In the scenario shown in a in, when the stylus receives, in the step shown in S, a press operation (or a long press operation) or the like performed by the user in the preset region, the stylus may send an identification result corresponding to the press operation to the electronic device through S, so that the electronic device displays a laser spotin the step shown in S. The user may simulate the laser pointer by using the stylus, and provide a visualization demonstration during service presentation.

9 FIG. 901 In an interface displayed on the electronic device shown in a in, the interface may be a first slide, and the interface may include the laser spotthat indicates information that a page is page 1, text information displayed as an introduction to the stylus, information displayed as shared by: user A, and time information that indicates that the time is Jul. 7, 2022.

9 FIG. In a possible implementation, in the scenario shown in b in, when the user ends the press operation on the preset region of the stylus, the electronic device may cancel displaying the laser spot.

It may be understood that the user may simulate, based on the press operation on the preset region of the stylus, the laser pointer to display the laser spot in the electronic device, and improve accuracy of press operation identification.

In another implementation, the user may alternatively implement page flipping control on the electronic device based on the trigger operation performed by the user on the stylus.

10 FIG. For example,is a schematic diagram of scenarios in which page flipping is controlled based on a stylus according to an embodiment of this application.

10 FIG. 10 FIG. 10 FIG. 704 705 706 In the scenario shown in a in, when the stylus receives, in the step shown in S, a slide operation that is performed by the user in the preset region and that is toward a position away from a tip of the stylus, the stylus may send an identification result corresponding to the slide operation to the electronic device through S, so that the electronic device performs page flipping in the step shown in S. For example, the electronic device may implement flipping to a next page. In this case, the electronic device may switch from an interface displayed on the electronic device shown in a into an interface displayed on the electronic device shown in b in.

10 FIG. 10 FIG. 10 FIG. 10 FIG. 704 705 706 2 In the scenario shown in b in, when the stylus receives, in the step shown in S, a slide operation that is performed by the user in the preset region and that is toward a position close to a tip of the stylus, the stylus may send an identification result corresponding to the slide operation to the electronic device through S, so that the electronic device performs page flipping in the step shown in S. For example, the electronic device may implement flipping to a previous page. In this case, the electronic device may switch from an interface displayed on the electronic device shown in a into an interface displayed on the electronic device shown in b in. The interface displayed on the electronic device shown in b inmay include information that indicates a page, an introduction to a definition of the stylus, and the like.

8 FIG. In a possible implementation, when the user adsorbs the stylus to a bottom of the electronic device, or the user disables a switch of demonstrating the page flipping stylus mode in the interface shown in b in, or the user taps the touch film for a plurality of times in the stylus, the stylus may exit the page flipping stylus mode.

It may be understood that the user may control, based on the slide operation on the preset region of the stylus, the electronic device to perform page flipping, and improve accuracy of page flipping identification.

10 FIG. 10 FIG. It may be understood that the stylus may alternatively control the electronic device based on an orientation of the tip of the stylus. In the interface shown in a inand the interface shown in b in, when the tip of the stylus faces up and when the stylus receives the slide operation that is performed by the user in the preset region and that is toward the position away from the tip of the stylus, the stylus may control the electronic device to flip to a next page. Alternatively, when the tip of the stylus faces up and when the stylus receives the slide operation that is performed by the user in the preset region and that is toward the position close to the tip of the stylus, the stylus may control the electronic device to flip to a previous page. A gyroscope sensor or the like for detecting an orientation of the stylus may be disposed in the stylus.

In a possible implementation, when the tip of the stylus faces down and when the stylus receives the slide operation that is performed by the user in the preset region and that is toward the position close to the tip of the stylus, the stylus may control the electronic device to flip to a next page. Alternatively, when the tip of the stylus faces down and when the stylus receives the slide operation that is performed by the user in the preset region and that is toward the position away from the tip of the stylus, the stylus may control the electronic device to flip to a previous page.

It may be understood that the control of the electronic device by the stylus in different orientations of the stylus and based on different trigger operations on the preset region in different orientations is merely used as an example, which shall not be construed as a limitation on embodiments of this application.

7 FIG. Based on the content described in the embodiment corresponding to, in this embodiment of this application, based on identification, by the stylus, of an operation on the preset region of the touch film, a false touch caused when the user triggers another position of the touch film can be avoided, and accuracy of controlling the electronic device by the user by using the stylus can be improved.

In a possible implementation, when document content, web content, or the like is displayed on the electronic device, the stylus may alternatively implement continuous page flipping control on a cursor in the electronic device, or for the document content, the web content, or the like.

11 FIG. For example,is a schematic diagram of other scenarios in which page flipping is controlled based on a stylus according to an embodiment of this application.

11 FIG. 11 FIG. 11 FIG. 1101 In the scenario shown in a in, the electronic device may display document content, and the document content may include a cursor. The interface displayed on the electronic device may further include a control that indicates to complete document editing, a save control, an undo control, a redo control, a control for exiting a document, a control for flipping to a previous page, a control for flipping to a next page, an identifier that indicates a position of currently displayed content in the document, and the like. Document content displayed on the electronic device in the scenario shown in b inmay be different from the document content displayed on the electronic device in the scenario shown in a in.

11 FIG. 11 FIG. 11 FIG. 704 705 706 In the scenario shown in a in, when the stylus receives, in the step shown in S, a slide operation that is performed by the user in the preset region and that is toward a position away from a tip of the stylus, the stylus may send an identification result corresponding to the slide operation to the electronic device through S, so that the electronic device continuously moves down or controls the cursor to continuously move down in the step shown in S. Further, when the user stops the operation on the preset region, the electronic device may end control on the cursor. For example, the electronic device may control movement of the cursor based on the slide operation performed by the user on the stylus. For example, the electronic device may display an interface displayed on the electronic device shown in a inwhen the user does not perform an operation on the stylus, and display an interface displayed on the electronic device shown in b inwhen the user ends the operation on the stylus. It may be understood that the movement of the cursor drives a change of display content on a page.

In a possible implementation, when the stylus receives the slide operation that is performed by the user in the preset region and that is toward the position away from the tip of the stylus, the stylus may alternatively control a page displayed on the electronic device to be continuously flipped to next pages. Further, when the user stops the operation on the preset region, the electronic device may end the page flipping operation.

11 FIG. 11 FIG. 11 FIG. 704 705 706 Accordingly, in the scenario shown in b in, when the stylus receives, in the step shown in S, a slide operation that is performed by the user in the preset region and that is toward a position close to a tip of the stylus, the stylus may send an identification result corresponding to the slide operation to the electronic device through S, so that the electronic device continuously moves up or controls the cursor to continuously move up in the step shown in S. Further, when the user stops the operation on the preset region, the electronic device may end control on the cursor. For example, the electronic device may control movement of the cursor based on the slide operation performed by the user on the stylus. For example, the electronic device may display an interface displayed on the electronic device shown in b inwhen the user does not perform an operation on the stylus, and display an interface displayed on the electronic device shown in a inwhen the user ends the operation on the stylus.

In a possible implementation, when the stylus receives the slide operation that is performed by the user in the preset region and that is toward the position close to the tip of the stylus, the stylus may alternatively control a page displayed on the electronic device to be continuously flipped to previous pages. Further, when the user stops the operation on the preset region, the electronic device may end the page flipping operation. A specific process is similar to a manner in which the stylus controls the movement of the cursor in the electronic device. Details are not described herein again.

11 FIG. 11 FIG. In a possible implementation, the stylus may alternatively control the electronic device based on an orientation of the tip of the stylus. In the interface shown in a inand the interface shown in b in, when the tip of the stylus faces up and when the stylus receives the slide operation that is performed by the user in the preset region and that is toward the position away from the tip of the stylus, the stylus may control the page displayed on the electronic device to be continuously flipped to next pages (or the cursor displayed on the electronic device continuously moves down). Alternatively, when the tip of the stylus faces up and when the stylus receives the slide operation that is performed by the user in the preset region and that is toward the position close to the tip of the stylus, the stylus may control the page displayed on the electronic device to be continuously flipped to previous pages (or the cursor displayed on the electronic device continuously moves up).

In a possible implementation, when the tip of the stylus faces down and when the stylus receives the slide operation that is performed by the user in the preset region and that is toward the position close to the tip of the stylus, the stylus may control the page displayed on the electronic device to be continuously flipped to next pages (or the cursor displayed on the electronic device continuously moves down). Alternatively, when the tip of the stylus faces up and when the stylus receives the slide operation that is performed by the user in the preset region and that is toward the position away from the tip of the stylus, the stylus may control the page displayed on the electronic device to be continuously flipped to previous pages (or the cursor displayed on the electronic device continuously moves up).

On this basis, based on the identification, by the stylus, of the operation on the preset region of the touch film and the orientation of the stylus, a false touch caused when the user triggers another position of the touch film can be avoided, and accuracy of controlling the electronic device by the user by using the stylus can be improved.

It may be understood that the interface provided in this embodiment of this application is merely used as an example, which shall not be construed as a limitation on embodiments of this application.
